A patented structured diaphragm, which was stress-optimized using finite element analysis, afflords the N-838.18 laboratory vacuum pump high pneumatic performance — despite its small size —as well as long service life. Depending on the model, it can achieve an ultimate vacuum as low as 12 mbar absolute and can pump up to 37 L/min. Components that come in contact with the pumped fluid can be made of several different materials, and a version with a PTFE-coated diaphragm is available for transferring aggressive gases.
